what is protobiont.....
Answers
Answer:
protobiont (plural protobionts) An aggregation of organic molecules, surrounded by a membrane, that abiotically coalesces into resemblances of living matter; thought to be the precursors of prokaryotic cells.
Example of a protobiont. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure and exhibit some of the properties which are associated with life, including simple reproduction, metabolism and excitability.
Prokaryotes dominated evolutionary history from 3.5 to 2.0 billion years ago. The early protobionts must have used molecules present in the primitive soup for their growth and replication. Eventually, organisms that could produce all their needed compounds from molecules in their environment replaced these protobionts.
